This patch is to deal with the extra bytes that the Qulsar Grandmaster appends at the end of the UDP payload for sync or delay response packets causing the packets to error out. The change is to use the PTP message length, rather than the UDP header length in suffix_post_recv().
The change conforms to Annex E.1 (IPV6) of the IEEE spec. Included is an explanation from Qulsar on why are they adding the additional bytes to the UDP payload. https://qulsar.helpscoutdocs.com/article/74-why-are-there-4-bytes-after-the-ptp-message Signed-off-by: Ashwin Shah <ashwin.s...@nokia.com> --- msg.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/msg.c b/msg.c index d1619d4..6d5ca37 100644 --- a/msg.c +++ b/msg.c @@ -422,7 +422,7 @@ int msg_post_recv(struct ptp_message *m, int cnt) break; } - err = suffix_post_recv(m, cnt - pdulen); + err = suffix_post_recv(m, m->header.messageLength - pdulen); if (err) return err; -- 1.7.9.5
